Ambient Conditions: 31 F @ surface, RH 64%, overcast, average noise, PC off ( 0 dB loss)

I mainly uploaded this 30 minute log for fun... Since we're now in a slight warming trend, I expect ever better performance despite this broadcast being aimed slightly east of north at 7 degrees.

Voice of Nigeria 15120 kHz reception near Atlanta, Georgia, USA

This afternoon's last hour reception report - 4.27% audio decoded, max SNR about 9 dB (the value in the log window is an incorrect DReaM spurious number).

30 minute log ... I'm pleased that the engineers at Abuya use mode C during the winter season in the northern hemisphere although the bit rate could be a bit higher.

In my opinion during the years I have listened to DRM Mode C has not proved to be a runner. And this 9 kbps is a pain in the ear. At the beginning tonight the audio modulation level was about 15 dB below the normal for DRM so I had to set the volume control in my PC to maximum to be able to hear anything. Later there was the opposite - 10 to 15 dB over the normal modulation level so my laptop almost jumped off the table.

94.3% decoded audio and the max. SNR was 18.62 dB. The Doppler rose steeply at the end of the transmission and the decoded "audio" went down the drain.
